Optional Sunroof Version Shown
If your vehicle is equipped with the DIC, it will show information about the vehicle and the surroundings. It is located in the headliner between the sun visors.
RESET: You can reset the AVG ECON, FUEL USED or AVG SPEED trip computer modes by pressing and holding this button for three seconds while you are in the mode you wish to reset. A chime will sound to confirm that your requested change has been made and all the segments of the display will briefly light up. To change the display to a metric or English reading, press the RESET and MODE buttons at the same time. Hold them down for three seconds and the display will change. A chime will be heard to confirm the new selection. The reset button can also be used to manually calibrate the compass. See "Manual Compass Calibration" later in this section. The reset button can be used to set the compass zone variation. See "Compass Variance" later in this section.MODE : Press this button to cycle through three modes of operation: Off, Compass/Temperature and Trip Computer mode.
| • | Off: No driver information is displayed in this mode of operation. |
| • | Compass/Temperature Mode: One of eight compass readings and the outside temperature are displayed. If the temperature is below 38°F (3°C), the word ICE is displayed for two minutes. |
| • | Trip Computer: Pressing the MODE button cycles through the five displays. Press the MODE button after the last Trip Computer display to return the DIC to the OFF mode. |
Compass Variance
Compass variance is the difference between magnetic north and geographic north. In some areas of the country, the difference is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set.
Setting the Variance
Turn the ignition on and cycle the DIC to the Compass/Temperature mode. Press the RESET button for about five seconds. The last entered variance zone number and VAR will be displayed. Press the MODE button until the proper variance zone number on the map is shown. Press the RESET button to set the new variance zone and resume normal operation.
All the display segments will be illuminated briefly to acknowledge the change in zone number. A chime will sound to confirm that the new zone number has been set.
Automatic Compass Calibration
The compass is self-calibrating, which eliminates the need to manually set the compass. When the vehicle is new, the calibration process may not be complete. In these cases CAL will be displayed, and all segments of the compass will be illuminated where the compass reading is normally displayed.
To calibrate the compass, in an area free from large metal objects, make one to two 360° turns. The calibration symbol will turn off and the compass reading will be displayed.
Manual Compass Calibration
If the compass appears erratic and the calibration symbol does not appear, you must manually put the compass into the calibration mode.
Turn the ignition on and cycle the DIC to the Compass/Temperature mode. Press the RESET button for at least 10 seconds until the calibration symbol appears and all segments of the compass display are illuminated. A chime will sound to confirm that the calibration mode is active. Release the button and complete two or three 360° turns in an area free from large metal objects. The calibration symbol will turn off and the compass reading will be displayed. A chime will sound to verify that the calibration is complete.
Error Displays
| • | An error of the speed sensor or fuel sender will cause -E- to be displayed. |
| • | In the absence of vehicle communications, a dash - - is displayed. |
If one of these error messages appear, see your GM dealer.
